The specimen MPCN-PV 69 consists on a small to midsized theropod skeleton composed by a partial premaxilla, three probable dorsal vertebrae, fused sacral vertebrae, the proximal half of both left and right humeri, the distal portion of the pubis, and an incomplete pedal ungual phalanx, plus some indeterminate fragments. Due to the grade of fusion of the neural arches to the centra, the specimen corresponds probably to an adult or at least to a subadult. The total length of the skeleton is difficult to specify because it is highly fragmented, but is estimated to be between 3 and 5 m long
